When to call us in Preston Candover
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Signs it’s time to call us include:
- Gaps between new skirting and floors
- Frame joints opening as the plaster dries
- Joints pulling apart as timber shrinks
- Kitchen sealant that has pulled off the wall
In and around Preston Candover, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic for homes and businesses in Preston Candover
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. We are often asked to deal with joints pulling apart as timber shrinks and new-build shower sealant that has already split, on bathrooms & en suites, skirting & floors and kitchens.
In a village or hamlet like Preston Candover, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
A 12-month guarantee comes as standard, so you are covered after we have gone.

What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
What we can’t put right
A few problems are outside what sealant work can do:
- Structural cracks in walls or ceilings
- Disputes or warranty claims with your builder
- Broken tiles or a split tray
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
What we seal
- Kitchens
- Windows & doors
- Bathrooms & en suites

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Report sealant problems to your builder during the snagging period
- Keep photos and emails about snagging items
- Act quickly if a seal starts to leak
- Keep water off fresh sealant until it has cured
Don’t stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
